Pls help 10 pnt X= 6 3.75 2

kolezko [41]

4 × ( x + 4 ) = 3 × ( 3 + 5 )

4 × ( x + 4 ) = 3 × 8

Divide both sides by 4

x + 4 = 3 × 2

x + 4 = 6

Subtract both sides 4

x = 2

In 2001 the mint indoor pool vault record was 20 and 1/6 the women’s record for the indoor pool vault was 15 and 5/12 FT what is

blondinia [14]

Answer:

35 and 7/12 feet is the combined height of the two records.

Step-by-step explanation:

Height of the indoor pool vault record for men = 20 and 1/6 ft = $\frac{121}{6} ft$

Height of indoor pool vault record for women = 15and 5/12 ft = $\frac{185}{12} ft$

The combined height of the two records :

$\frac{121}{6} ft+\frac{185}{12} ft$

$\frac{121\times 2}{6\times 2} ft+\frac{185}{12} ft$

$\frac{242}{12} ft+\frac{185}{12} ft$

$\frac{242+185}{12} ft=\frac{427}{12}=35\frac{7}{12}$

35 and 7/12 feet is the combined height of the two records.

10p - (3p - 4) = 4(p + 1) + 9

andrezito [222]

Answer:

p = 3

Step-by-step explanation:

distribute parenthesis on both sides of the equation

10p - 3p + 4 = 4p + 4 + 9 ( simplify both sides )

7p + 4 = 4p + 13 ( subtract 4p from both sides )

3p + 4 = 13 ( subtract 4 from both sides )

3p = 9 ( divide both sides by 3 )

p = 3
